Project Description

The M1 Productivity Package consists of three projects including:

Kariong to Somersby (and Kariong interchange) — widening of an 8 kilometre section of the M1 Pacific Motorway between the Somersby and Kariong interchanges from four lanes to six lanes and upgrades to three of the four interchange ramps that provide the main arterial access to and from the motorway to the Central Coast Highway and the city of Gosford. This excludes a 1.5 kilometre section on the southbound carriageway between the Kariong interchange southbound exit and entry ramps;

Tuggerah to Doyalson — widening of 12 kilometres of the M1 Pacific Motorway between the Tuggerah interchange and the Doyalson interchange from four to six lanes and pavement strengthening; and

Weakleys Drive Intersection — upgrade of the intersection to increase capacity.


The M1 Productivity Package will reduce travel times, improve road freight efficiency and provide for the expected growth of tourism, commuter and freight traffic between Sydney and Newcastle.


The total cost of the project is $392 million. The Australian Government is providing $195.8 million towards the planning and construction of the package.
